SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 563,909, dated July 14,1896.

Application filed December 3 1895, Serial No. 570,934:- (No model.)

To aZZ whom it may concern.-

Be it known that 1', ROBERT 1. BROWN, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Spring-Motors; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as .will enable others skilled in theart to which it appertains to make and use the same. I

My present invention relates to motors and has especial reference tothat class of motors in which power is stored in springs andsubsequently utilized to do work of various kinds; and the inventionconsists in certain improvements in construction, which will be fullydisclosed in the following specification and claims.

In the accompanying drawings,which form part of this specification,Figure 1 represents a side elevation of my improved motor; Fig. 2, anend view; Fig. 3, a top plan view, and Fig. 4. a side view of the brakedetached.

Reference being had to the drawings and the letters thereon, A Aindicate the sides of the frame; B, the partition, middle, or centerpiece, and C O the transverse pieces which connect the sides A A andsustain the center piece in proper position. The sides are provided withextensions c, to which are secured wheels I), upon which the motor maybe rolled to change its position, extensions 0, which form feet for themotor to rest upon, and with handles (Z, by which it may be readilymoved. The frame is also provided with an extension at its upper end inwhich a governor is supported, as will hereinafter more fully appear.

lVithin the frame and on each side of the partition B are a series ofshafts 6, upon which are wound springs f one end of which is secured tothe shaft and the opposite end to rods 1 2 3 4i 5 6 '7 8 9, supported inthe frame. The shafts c are supported at each end in suitable hearingsin the sides A A'and in the center piece or partition B of the frame,with one end of said shafts extending through the side frames andsquared to receive a suitable key or wrench to wind the springsseparately, or the shafts maybe connected by applying gearwheels to saidends f of the shafts, and the whole train of shafts turnedsynchronously, and the springs wound in the same manner.

Each of the shafts c is provided with a gear wheel D, which intermesheswith the adjacent wheel, as shown in Fig. 1, so that the power of allthe springs is transmitted to the driving-shaft 10, and on each shaft issecured a ratchet-wheel g, with which a pawl 72, secured to one of thearms of the wheel D, engages. The power of the train of spring-actuatedshafts is. transmitted from the center shaft of the upper tier of shaftson each side of the motor by its gear-wheel D toa pinion 'i on each endof the shaft 11, and from shaft 11 power is transmitted to shaft 10 by amaster gear-wheel it, which engages a pinion Z on said shaft. The shaft10 is provided with driving-wheels m n, from which power is transmittedby a suitable belt engaging said driving-wheels.

On shaft 12, supported by the frame, is a master-wheel 0 and a pinion p,the working face of which pinion is equal to the width of themaster-wheel g on. shaft 1], and a like wheel '2' on shaft 13, and saidshaft 12 is laterally movable in its bearin to vary the speed of themotor by transmitting the power through pinion p on shaft 12 andmasterwheel 4' on shaft 13, or through master-wheel 0 on shaft 12 andpinion s on shaft 13. The shaft 12 is moved by a lever 1 attached to theshaft and fulcrumed to a bracket 21 on the frame and connected to ashifting-rod "If.

E indicates the governor, supported in the extension E of the frame ofthe motor, which extension is provided with a step in to support thelower end of a spiral shaft or wormgear g, which engages the gear-wheelr, and with a bar 5, through which a screw a" passes and engages theupper endof the worm-gear y to center the governor in the extension ofthe frame and compensate wear on the wormgear. On the upper end of theworm-gear is a sleeve b',which slides vertically on a squared portion ofthe worm as the balls 0 and arm (1 of the governor rise and fall, andthe lower end of said sleeve is provided with or forms a brake-shoe cwhich engages the plate 6 and forms a brake to vary the speed of themotor by frictional contact of the shoe and the plate. Should part ofthe load be taken off the machine, the increased speed of the motorcommunicated to the governor will cause the arms and balls of thegovernor to rise by centrifugal force, and they will depress the sleeve1'), to which the inner ends of the arms d are pivotally secured andfulcrnmed in a disk f on the shaft of the Wormgear.

F indicates a brake, whose arms g h are pivotally connected to the frameat i, and on the inside of each arm is a block or shoe k l, whichengages the shaft 10 to stop the motor. Pressure is applied to the shaftby a screw-nut in, which engages a bolt a, connected to the lower end ofthe arm 71- and extends through the extension 0 of the arm g, and uponwhich the nut m bears.

The extension 0 of the arm g maybe connected by a rod or cord p to themachine being operated, so that the brake may be applied withont goingfrom the machine to the motor.

The arms of the brake are separated and the brake released by springs q'1', connected to a lug s, projecting from the frame, the spring q beingthe stronger of the two to raise the upper and long arm q, while thespring 0" counterbalances the action of the spring q to prevent theblock Z on the arm h engaging the shaft.

Having thus fully described my invention, what I claim is 1. Amotor-frame provided with an extension having a step or shaft bearingtherein, a governor supported in said extension and consisting of avertical spiral shaft or wormgear resting in said step, avertically-movable sleeve on said shaft having abrake-shoe at its lowerend, a fixed friction-disk below said sleeve and an adjusting-screwengaging the upper end of the shaft, in combination with spring actuatedshafts connected by suitable gearing, a power-shaft and alaterally-movable shaft connected to the governor.

2. A motor having a plurality of spring-actuated shafts and apower-transmitting shaft, in combination with a brake comprising a pairof arms pivotally connected at one end and provided with brake-shoes,means for drawing said arms toward the shaft and springs of differenttension to separate the arms and release the brake.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT I. BRO\VN.
